产品概述
LH45X-16系列限流止回阀主要用于多 泵并联采用改变台数的方式进行流量调节的系统中，安装在水泵的出口，起限制输泵流量，稳定扬程。使水泵在高效区内工作，防止低扬程大流量水泵过载烧坏电机。
 
产品特点
1、支持水泵工作点在高效区内工作
2、限制水泵大流量，低效率时运行
3、微阻缓闭止回停泵时，关闭无水锤现象
4、防止水泵过载超额定电流烧坏电机
5、无级调节扬程功能
6、限制扬程可调范围0.1-0.6MPa，出厂时设定在0.1MPa
7、介质温度： 0-150℃
 
安装调试
1、介质流动方向应与阀体箭头方向一致；
2、外接导压管装置出厂前均通过压力试验，安装时严禁损伤导压装置；
3、阀.上的1}2管接头应安装在水泵入口处；
4、可水平安装也可以垂直安装；
5、当需求扬程大于0.1 MPa时，先逆时针把四通开大，然后在顺时针逐渐关闭调压阀，关闭过程中出口压力会逐渐增大，直至出口压力为需要扬程时，即完成初调节，反复启闭水泵2-3次，每次运行3-5分钟，出口压力不变即完成调试工作；
6、视水质情况应经常检查出口压力值，当出口压力小于设定值时。应开启过滤器排除污物。
